Hi,
Backups (Dynatrace Managed): Dynatrace writes cluster backups to a shared NFS path you provide. There’s no product-side feature that automatically encrypts those backup files—the encryption is up to your storage (e.g., encrypt the NFS volume / disks / filesystem). Docs and forum guidance focus on mounting a shared backup volume across all nodes, not on app-level backup encryption.
Here is topic related to this on community: Managed Cluster backup to NFS
Cassandra & Elasticsearch at rest (Dynatrace Managed): There is no built-in data-at-rest encryption for these databases in Managed. Dynatrace does encrypt certain sensitive values (like credentials) inside Cassandra, but full at-rest encryption of the data stores is not enabled by default. If you need encryption at rest, place Dynatrace data on encrypted disks/volumes at the OS/storage layer. Also note: inter-node/client encryption for Managed Cassandra is not enabled by default due to performance trade-offs.
